A- 16 Claims. (Cl.5776) Y The invention' relates to spinningbuckets Figure 9 is a vertical section taken on line '1I-II of Figure 1,

adapted to receive artificial fllamentary material.

In removing the "cake, particularly of freshly spun maments, from the type of spinning bucket heretofore employed, injury frequently results from the insertion of the hands of the operators f into the center of the cake when they at times reach. in and grab the interior windings of the cake to assist in withdrawing it from the spinning bucket, At times, the cake does not fall out of the bucket as a unit so that. the loosened cake "ail'ords greater opportunities for 'tangling and snagging during the subsequent handling and transpo ation. Again, the rubbing of the cake against i'ect the exterior windingsthereof. Even those cakes of the best form and the least ailected by i e interior wall of the'buckets astheyv yare withdrawn therefrom may detrimentally af-v IX-IX of Figure 8. i

The embodiment of Figures 1 and 2 comprises a base plate 2 provided with a hub I adapted to iit on the spindle 4 of a motor in the manner oommonly employed heretofore and `a container for v provided with a foot 6 in the form of a portion of an annuius which preferably extends inwardly Y at least a distance corresponding to the `thick ness of the cake to be built within the box. The central portion 1 of the base plate isl elevated above the outer annular portion thereof by a jacket for the illamentary material during handing and transportation thereof subsequent to the collection of the lamentary material therein.

Further objects of the invention will be apparent Figure 1 is a'plan view of one embodiment of the invention with apart ofthe cover cut away, Figure 2 vis a vertical cross-section on the line distance substantially equal to the thickness of the feet of the segments so that the-bottom of alignment the projections 9 vfrom the 'feet of the segments with the spaces' I0 between the projections 8 on the central platform 1 and then turned with respect to the base so that the projections of the segments are locked beneath the over-hanging projections from the central platform as shown in Figure l. iAnnular recesses, Il

The slots4 I4` of Figure 3, Figure 5 is a top plan view of a third embodithe' bayonet joint should be so arranged that the nient, l rotation imparted to the basel by the spindle 4 tends to force the projections I5 on the base into the llocking vposition within the slots. The slots I4 shown in Figures 1 and 2 are arranged for operation with a spindle rotatingin a counter-clockwise direction as viewed from the top. Toy fa- Y cilitate the application of the cover and removal of it from the' segments, the segmentsare'provided with a taper outwardly from top to bottom and the interior of the hood-like cover is provided with annular ridges I6 which extend inwardly and are adapted to tightly engage'the external circumference of the segments when the cover is locked.

in place. Instead of having two annular inwardly extending ridges I6 within the cover, the internal wall surface of the cover may bev formed as a conical surface with a taper complementaryto provided with the usual opening II adapted to permit the reciprocation of the funnel guide along l the axis of the spinning pot The spinning pot of Figures 1 and 2 is shown ready for operation.k After the completion ofthe 'collection of the cake within the pot, the cover in theirjeceding embodiment, the walls of the segment, the ,cover and the basemay be provided with liduid discharge channels in the usual manthat of the segments. The top of the cover'isalso nel'.

In the embodiment ofFlgures 3` and'fi; the segmental walls maybe-encircled lb y one or more elastic rings afterthe completion of thecollection of' the'fllaments.thereimg' 'I'here'aftenl the cover may be remov'd'iromthe segmental receptacle andthe receptacle may 4beremoved from .the base I8 and serve for transporting the cake.

If desired, the cover may be left in place on the I3 may be removed by turning it With'respect to the baseg2 until-the bayonet joint Il, I5 is unlocked. It is to be noted that the turning move? ment made in unlocking the bayonet joint is inf sufficient to unlock the joint '(8, 9) between the feet of the segments andthe central platform so that upon lifting the cover from the base, the segments are necessarily held to the base. After removal of the cover, the segments 5 are still held segmental receptacle 'as an additional projection during transportation.

A third embodiment 'is shown in Figures 5 -to 7. This embodiment is similar to that of Figures 1 land 2 except with respect to the interlocking arrangement-between the base 2and the feet 6 of the. segments.l *Instead* of: having the locking .201

projections on the centralplatform as inFigures 1 and 2, the embodiment of Figures 5 to 7 has a `plaincylindrical platforml surrounded by an annularV portion of the base which is provided with a plurality of upstanding sectors 25. Each unitarily by the elastic bands or springs I2. The

segments 5 may be removed from the base 2 with cake so that no damage is done tothe windings.

thereof. While no liquid 'discharge channelsl are may be provided with such discharge channels in the form of relatively small perforations generally extending radially therethrough.

In Figures 3 and 4 a second embodiment is shown in which the spinning pot comprises the base I8 segmental walls I9, and a cover 20. In this embodiment, each segment constitutes a fourth of a cylindrical surface provided with a foot 2| in the form of a quadrant of a circle. The four feet rest upon the base and form the' bottom of the filament receiving container. The segments are provided with interlocking ioints for fastening it to the base and to the cover respectively. Both interlocking connections are similar and are constituted essentially of a type of joint used in fastening closures to jars and bottles. This interlockingconnection is: shown more particularly in the cross-sectional `view of Figure 3 and consists essentially'in providing the of these sectors 25 (and there are four shown in the drawings) Aoccupies approximately a angle (that is, about half a quadrant) and has one of its, radial faces .28 verticalA and the other radial' 'face'21 formed asanfundercut groove. Each' of the rsegments has itsfoot vprovided with acomplementary sector 23. extending downwardlytherefrom, again with one'of its radial faces 2S vertical andthe otherof its radial faces 30 as an undercut groove. The result is that the segments may be placed upon the base with their sectors alternating with the upstanding sectors upon the base and the cover-placed upon the as- `sembly for collection of yarn. After' completion 404 shown in the bucket construction, both the segments 5 and the cylindrical wall of the cover I3 of the collection of the iilamentary material, the turning of thecover with respect to the base to unlock the bayonet Joint Il, I5 turns theseg'-v ments with respect to the base so that the undercut radial faces 21 and 300i the sectors of the base and the feet of the segments are locked together. Thereupon, lifting of the cover ei'ects Aits removal without also removing the segments with it. Afterwards, the segments'may be lifted as' a unit from the base merely by effecting a neck 22 of the segments with a ridge 23 which.

is adapted to cooperate with a groove 2l formed in an overhanging flange of the cover. The

ridge 23 may be tapered oif as clearly shown in Figure 3 in orderto provide for tight engagement with the complementary tapering of the groove 24 in the angeof the cover.' Alternatively, the` ridge 23 may extend in a helical direction so that `slight reverse turning movement.

tral platform is reduced to a relatively small centeringbutton. The bottom of feet of the seg-y ments is provided with an annular groovell whose sidewalls are verticalfor a portion of the grooye/"and sloped at another portion 32 in the manner shown to cooperate with a tongue 33 vex tending upwardly from-the .base 2 to form a dove 'tail':|oi nt.V vA sufllcient length of the groove 3l should have plain vertical sides to permit the.

f ree entrance of the tongues 33 on the base when thesegmen'ts are placed upon the base. While preferred embodiments of the invention have been disclosed, the description is intended to be illustrative only, and it is to be understood that changes land variations may be made without departing from vthe spirit and scope of the invention as defined by thesappended claims.
